Abstract
Apparatuses and methods for level shifting in a semiconductor device are described. An example apparatus includes: a splitter circuit that operates on a first voltage potential to produce a first signal having a first polarity and a second signal having a second polarity that is substantially opposite to the first polarity; an one-shot pulse circuit that operates on the first voltage potential to produce a first one-shot pulse signal responsive to the first signal and a second one-shot pulse signal responsive to the second signal; and a logic circuit configured to operate on a second voltage potential to produce a third signal responsive to the first and second one-shot pulse signals, the second voltage potential being different from the first voltage potential.
Claims8
A level shifter circuit comprising:
- a splitter circuit configured to operate on a first voltage potential to provide a first signal having a first polarity and a second signal having a second polarity that is substantially opposite to the first polarity;
- a one-shot pulse circuit configured to operate on the first voltage potential to provide a first one-shot pulse signal responsive to the first signal and a second one-shot pulse signal responsive to the second signal;
- and
- a logic circuit configured to operate on a second voltage potential to provide a third signal responsive to the first and second one-shot pulse signals, the second voltage potential being different from the first voltage potential.
